The Toshiba has 2.4GHz 802.11n Wi-Fi and while it ships with Bluetooth 2.1, this will be shortly upgraded to Bluetooth 3.0 by way of a software update, the manufacturer said.

The NB520 will be accompanied by the NB500, a more basic model with a single-core, 1.6GHz N455 CPU, 1GB of DDR 2 and none of the audio extras of the NB520.

The NB500 offers up to eight hours of battery life, Toshiba claimed, while the NB520 can manage ten, both using a six-cell battery.

There's no word on pricing, but the two netbooks will be out at the end of January 2011. The two come with what Toshiba described as "the same blue, brown or green rubber-textured exterior, as well as a sleek resin black finish". ®
